Mixing & Applying Microne Base Plus
If you chose the “Microne Plus” option when you ordered, you will have 1 bottle for every tub of Microne that you have. Adding 1 x Microne Plus to each of the tubs, will make the surface stronger, more resistant to heat and more stain resistant.
Add 500g Microne Plus to 10kg Tub of Microne & mix well with a microcement mixer. That’s a mix ratio of 1:20.
Once mixed, you’ll have 45 minutes to 1 hour working time, so only mix what you need and make sure you’re ready to apply it straight away.
Applying the 1st Coat of Microne Base Plus
Using a Microcement Trowel, work your way out from one corner creating a random edge pattern. Keep trowel movements small and random, avoid long sweeping arches – as these will show through to your final finish.
Use the grain in the microcement as your level – if you apply the microcement thicker than the size of the grain, the finish won’t be as strong and will require a lot more sanding. Run the trowel back over each section that you have put down to smooth it out and remove excess product. You should still be able to see the mesh after after applying this coat.
Completely coat each surface without stopping. For complete rooms, start with ceilings, then walls from left to right (or right to left) and then the floor.
Run your finger or a corner trowel along internal corners to push the microcement into the corner and then gently trowel away the excess product.
Mixing 2nd Coat of Microne Base Plus
Add 500ml Microne Plus Comp B to 10kg Microne Base with Colour and mix well.
We have added the colour to the tubs but not mixed it in. The colour is at the bottom of the tub so shen you open the tub, it may look like there’s no colour in there at all. But when you start mixing, it will gradually change colour to the one you have chosen.
Unlike the Top Coats, the colour for Base Coats is not an accurate match to the swatch, it’s just enough to take it in the right direction before Top Coats are applied.
To loosen the mix, mix thoroughly with a microcement mixer head attachment on a cordless drill. If it still feels stiff, you can add up to 10% water to loosen & mix further. That’s a maximum of 1l per 10kg.
Let the mixture rest for a few minutes before applying.
Applying the Microne Base Plus
Apply the 2nd Coat of Microne Base Plus in exactly the same way as the 1st coat.
Leave to Dry
This should take around 3 hours but may vary depending on temperature and humidity.
Sand with 40/80 Grit Sand Paper
Once the base coats are dry and before you apply your Top Coats, you need to make sure the Base Coats are completely flat. You need to use a strong sand paper, like Silicone Carbide, to prevent colour from the disc transfering to your work.
Flatten the Microne Base with a 40 or 80 grit sand paper. An orbital sander is ideal, but, for smaller areas, you can do it by hand.
Use the sand paper to remove ridges and drips that have dried in the microcement.
The top coats are very thin so any ridges or imperfections in the base coats will be visible in the top coats. Take your time to get it completely flat before moving on to the next step.
Vacuum the surface to remove all dust and debris. Do not wet the microcement.
